We determine optimal electrode shape and size of lateral-field-excited (LFE) thickness-shear resonators. The determined electrodes are optimal in that they satisfy the criterion for Bechmann's number in every direction. Numerical and graphical results are provided for AT-cut quartz, (yxl)- 45°langasite, and (yxl)-16.5°LiTaO(3) LFE resonators. The optimal electrodes of AT-cut quartz LFE resonators are also compared with those of AT-cut quartz thickness-field-excited (TFE) resonators.
我们确定了横向场激励（LFE）厚度剪切谐振器的最佳电极形状和尺寸。确定的电极是最佳的，因为它们在各个方向上都满足 Bechmann 数的标准。为 AT 切石英、（yxl）-45°langasite 和（yxl）-16.5°LiTaO(3) LFE 谐振器提供了数值和图形结果。还将 AT 切石英 LFE 谐振器的最佳电极与 AT 切石英厚度场激励（TFE）谐振器的电极进行了比较。
